Abstract

An optical splitting apparatus includes an enclosure, an even optical splitter and an uneven optical splitter that are disposed in the enclosure. A light inlet and a plurality of light outlets are disposed on the enclosure, and fiber adapters are disposed on the light outlets. The light inlet, the even optical splitter, the uneven optical splitter, and the light outlets are connected, so that optical paths are formed between the light inlet and the light outlets by using the even optical splitter and the uneven optical splitter. The light inlet is connected to at least one of a light input end of the even optical splitter and a light input end of the uneven optical splitter, and the fiber adapter on the light outlet is connected to at least one of a light output end of the even optical splitter and a light output end of the uneven optical splitter.
